HVAC

  • Elke dag worden er overal ter wereld frequentieregelaars geïnstalleerd in diverse verwarmings-, ventilatie- en airconditioningtoepassingen (HVAC) en waterstuwingstoepassingen in zowel nieuwe als bestaande gebouwen, en in infrastructuursystemen. Ze verbeteren de luchtkwaliteit en het comfort in een pand, bieden betere regel- en energiebesparende mogelijkheden, bieden een betere bescherming van bedrijfsmiddelen, verlagen de onderhoudskosten en verhogen de betrouwbaarheid.

     
    De dagelijkse schommelingen in de belasting in HVAC-faciliteiten zijn aanzienlijk. Toerenregeling van elektromotoren is een van de meest effectieve maatregelen om kosten te verlagen. Door het gemiddelde toerental van een motor in bijvoorbeeld een pomp of ventilator met 20% te verlagen, is een energiebesparing van 50% te realiseren. Bij een verlaging van het gemiddelde toerental met 50% loopt de kostenbesparing op tot 80%.

    Verlaag de totale exploitatiekosten

    De energiekosten over de volledige levensduur hebben een enorme invloed op de totale exploitatiekosten. Zelfs kleine verlagingen in het energieverbruik kunnen leiden tot enorme kostenbesparingen binnen een relatief kort tijdsbestek. Over de volledige levensduur van de frequentieregelaar bedragen de initiële aanschafkosten slechts 10% van de totale exploitatiekosten; de overige 90% betreft energieverbruik, service en onderhoud.

    Functies als automatische aanpassing motorgegevens (AMA) en automatische energieoptimalisatie (AEO) zorgen ervoor dat uw frequentieregelaar altijd perfect is afgestemd op de aangesloten motor en wisselende belastingen. En omdat er slechts minimaal onderhoud vereist is, bieden Danfoss frequentieregelaars een korte terugverdientijd voor uw HVAC-investering en zorgen ze voor een aanzienlijke verlaging van uw totale exploitatiekosten. 

    Bereken het energieverbruik met de VLT® Energy Box

    De VLT® Energy Box software berekent zo nauwkeurig mogelijk de kosten, besparingen en terugverdientijd bij gebruik van Danfoss frequentieregelaars in HVAC ventilator- en pomptoepassingen. Met deze tool kunt u het energieverbruik van door Danfoss frequentieregelaars bestuurde HVAC-ventilatoren en -pompen vergelijken met het energieverbruik van andere debietregelmethoden.

    Toepassingen

    HVAC-systemen regelen de verwarmings- en koeleenheden in een gebouw om optimaal comfort te leveren. De condities worden geregeld door diverse toepassingen die allemaal gebruikmaken van frequentieregelaars. Hieronder vindt u enkele van de belangrijkste HVAC-gerelateerde toepassingen:
    Verwarming
    • Drukventilatoren en afzuigventilatoren voor ketels
    • Primaire heetwaterpompen
    • Convectoren
    • Warmteterugwinningssystemen
    Ventilatie
    • Luchtbehandelingskasten, dakunits, toevoer- en afzuigventilatoren
      • Ventilatiesystemen met variabel/constant luchtvolume
      • Rookventilatie-, brandbestrijdings- en trappenhuisventilatiesystemen
    • Ventilatiesystemen voor parkeergarages
    • Keukenventilatiesystemen
    Koeling
    • Koelwaterpompsystemen
      • Primaire/secundaire pompen
      • Variabel debiet met alleen primaire pompen
    • Convectoren
    • Warmteterugwinningssystemen
      • Koeltorenventilatoren, condenspompen
    • Koelcompressor
    Vers water
    • Boosterpompen
      • Enkelvoudige of parallelle pompen
